I am creating images in Photoshop with a transparent background. I am calling them into flash dynamically with actionscript 3 but the transparency has a white ghostly look to them. I can see the boxes move around on my ANDROID devices.
I found this tutorial and it helps: http://kb2.adobe.com/cps/128/tn_12804.html#main_Known_issues_with_transparent_bitmaps
HOWEVER I want to import the images dynamically and not have to bring each image in to flash and fix it. Any ideas on what settings will work when exporting from photoshop?
I found a "WORK AROUND" solution.
I created a transparent PNG TO COVER THE ENTIRE SCREEN. I loaded it in the second level
above the background image. There may be a ever so faint "ghosting" look but I can't tell by looking. One thing for sure it removed the boxes around the other transparent PNG files I am loading in. So that's great!
Please let me know if this helped you. Thanks

OK, I've read a lot of tutorials and even downloaded some examples, but for the love of Stackoverflow, I can't get my image to stretch like I want it to and I'm hoping that someone can help me out here.
I create an image that is to be the background of a button object in Android. Here is the image:
Now, I'd like for it to stretch to the desire size of the button, whether the button is 50x50dp or 200x100dp. One thing I don't want is the border to stretch as it will look distorted, so I want to specify not to include the border, but stretch everything else to the desired size of the button.
Can someone please show me where the black lines need to go in order to achieve my goal? Do I have to change my original image in order to achieve my goal?
Thank you in advanced.

It's very simple using this tool Android Asset Studio: Simple 9-Path Generator. Although no matter how you do it you will have stretching and distortion due to the textured (non-patterned) background. I would stay away from that style both personally and for usability.
I am trying to use the card_background 9-patch that is extracted from the play store apk and I am having trouble getting the 9-Patch to place itself correctly. Here is an image of my emulator running this problem. I am trying to make the typical card view that is used somewhat commonly now but this is just one of the problems I cannot work out how to fix.
My 9-Patch card_background:
I am also pretty sure the 9-Patch is setup incorrectly as according to the 9-Patch tool in /sdk/tools the entire two areas that I am using are both bad patches but I don't know what that means so I hope one of you can help to fix this.
I modified your image, I think this works:
Your 9-patch image stretches all the white/border correctly, but it has nothing but transparency at the bottom. If you want a gray shadowy area beneath it, you need to draw it there, below the white. Just make sure you don't extend the black stretch-bar down to it, or it will stretch as well.
Go into the sdk's nine-patch editor tool after you extract the png's from the apk and put them in their respective drawable folders. The tool can either be the one inside the /tools or, even better, the direct editor in Android Studio.
Modify the stretch regions for each image to your liking until it looks like an actual card. I had the same problem, until I went back and redid the stretch regions. For some reason, the png extracted from the apk didn't save the stretch regions when extracted.
You should have a shadow automatically appear from the given images, you DO NOT need to draw it yourself. Just make sure you don't include the corners and the shadow in the stretch region. And give a little bit of slack too.
I have been trying to change the color of the gray that surrounds my custom tabs, I have tried looking for the answer on YouTube:

http://www.youtube.com/watch?v=XMWlRXfKgtY
This helped me understand the process of 9-patch files but I must be doing something wrong for this not to work.
What I have tried doing so far:
In my project I see in the "Package Explorer" I see Android 4.1, which is in ...android-sdk/platforms/android-16. I opened that with winrar, went into res/drawable-mdpi and just to see if anything would change I replaced "tab_selected.9.png" and "tab_selected_v4.9.png" with the image of "tab_pressed.9.png". I then tried to compile my project just to see the same gray for the background of my tab buttons.
The current android project I am working on I placed the changed "tab_selected.9.png" and "tab_selected_v4.9.png" inside of my drawables folder and tried running it just to see the same thing.
Does anyone know what I am doing wrong, am I not compiling something or do I need to mess with different .9.png files? Or does anyone have a simple process just to change the gray color of these tabs? I guess the quick answer for me here is what would I have to do to get the image of "tab_pressed.9.png" to replace "tab_selected.9.png"
EDIT:
tab_selected.9.png
tab_pressed.9.png
Make sure the only pixels in the border are the 9-patch ones, either black (#f000 in ARGB) or fully transparent (#0000).
It's a normal to left some pixels with some transparency on those pixels that gets unnoticed at simple view.
This is a little tricky. Sometimes the stuff like the grey can creep in from the underlying Android layer. Sometimes things like tabhost have views that have to be overridden. I remember having to maek a selector drawable in XML to get the tabhost to work with custom items.
For a mobile website project I encountered a problem that (only on android browser), the gradient to transparency (smooth outer glow) does not look clean. Instead you can see clear edges around it. Strangely though it seems to disappear for as long as I scroll the page.

The problem does not occur on any Desktop Browser or on iOS Devices.
Thanks for your help!
UPDATE:
I found out, that the problem is called PNG Banding and only occurs with PNG-24 (24 bit) on the 16bit displays. As I cannot go with an 8-Bit Image (which would render fine) because of the quality loss, I still did not find a solution for the problem
I have also not found a solution to this problem.
In my case, I had a PNG with a white-to-transparent gradient that I would overlay on top of elements with solid background colours to give them a "shine" up top. No matter what I tried, there would always be banding on the Android browser (and no other browsers at all).
Before I even tried the PNG gradient, I tried doing so with CSS3, but that suffered from the same issue.
In the end, I was forced to create opaque PNGs with the white-to-transparent gradient layer merged with the colour layer. This meant I had to do the Photoshop equivalent of "hard-coding" each possible shine/shadow with whatever colour it would be on top of. Not the best solution, but it displays fine on Android browser without any banding and I needed do something, so yeah. :|
In photoshop, Save For Web. Choose PNG-8 bit. Dither Option: choose pattern or noise. This will smooth out the gradient banding.
I recently downloaded an app from the market called WunderList and it has this neat effect on a Edit Text for transparency
I am trying to recreating the same effect for one of my applications but I am not really getting anywhere. I initially thought it is just transparency but I was wrong. Now I have put an image with shadow as the EditText's BG an trying to set it's alpha. I am not sure If I am on the right path. I would appreciate any guidance on this.
I got this done through a custom 9patch image. Here's a sample result.
It's not close but I am getting closer.
That's actually the way we do it.
We use a 9patch PNG with transparency.
